"answer": "Anti-sybil: rate-limited issuance. Each identity solves a hashcash puzzle scaled to prior mints from the same /24 subnet. Step one, the node logs the subnet, issues a nonce. Step two, the client returns a SHA-256 digest with N zero bits, N rising 4 per 100 mints. Step three, mints cap at 3 per subnet per 24 hours; excess requests queue to the next window. Step four, the beacon voids bursts via timestamp checks. Cost: 10,000 proxies at $0.50 each burns $5,000 monthly, plus 2.1 GPU-hours per 1,000 mints. A violet river of proxy requests climbs one dune; the queue grows, the door doesn't.\n",
